Based on foregoing description, Fig. 1 illustratively shows a kind of application file source inquiry provided in an embodiment of the present invention Method, this method can perform by device that application file source is inquired, which can be terminal device, can also be located at In terminal device.
As shown in Figure 1, the flow specifically includes:
Step S101 obtains the title of destination folder under root.
Step S102, according to the name query folder name of the destination folder and the corresponding pass of application packet title System obtains and applies packet title corresponding to the title of the destination folder.
Step S103 applies packet title according to corresponding to the title of the destination folder, determines the file destination The title of the corresponding application of folder.
In embodiments of the present invention, for ease of description, will wish to inquire with file manager below autonavi this A catalogue be which application create for come describe application file source inquiry flow.
When scanning root discovery in file manager side has unknown file to press from both sides autonavi, unknown file folder is target File, so as to know the title autonavi of destination folder under root.In embodiments of the present invention, file destination Folder can be that unknown file is pressed from both sides, that is, file manager can not identify its corresponding Apply Names according to the title of file File.Folder name and the correspondence of application packet title can be inquired according to the autonavi at this time, which closes System can be located in public database, such as can set key as folder name, and value can be using packet title.Pass through Inquiry key is autonavi, can obtain the corresponding value of the key as com.autonavi.minimap, that is to say, that should The corresponding entitled com.autonavi.minimap of application packet of folder name autonavi.
After the packet title that is applied, file manager can be obtained this and corresponded to using packet title by system interface Apply Names " Amap ", and can show, be checked convenient for user.
It should be noted that if the value values obtained are inquired less than application, explanation is a underlying services class process, can be with It is shown as desired as process name.
Optionally, for the ease of file manager by the name query of destination folder to using packet title, Ke Yigen Above-mentioned folder name and the correspondence of application packet title are determined according to flow as shown in Figure 2.
As shown in Fig. 2, the specific steps of the process comprises:
Step S201 is obtained and is parsed journal file, determines the row information where the detection mark of destination folder.
Due to different size of log buffering areas, the log times length that can be stored is different, for example, 10s can be preserved, is All log can be got, can obtain log to be less than the random time of storage log times, for example, can be according to 5s once obtains log.
After the system of terminal device starts, fileDetectService (file finds service) cycle can be started Obtain log.The effect of the service is that cycle performs and obtains newest log output files.
After cycle obtains log, the log of acquisition is parsed line by line, when the content for being resolved to certain a line includes mesh When marking the detection mark of file, illustrate the partial information for including destination folder in the row information.It needs to carry out this journey It stores and is further processed.
Optionally, before the log files in the predetermined period are obtained, it is also necessary to first set the detection mark of destination folder Know, that is to say, that when the destination folder creates, setting detection mark.Then the directory path letter of destination folder is obtained The process number of breath and establishment file folder.Finally by destination folder detection mark, destination folder directory path information and The process number for creating the destination folder is attached according to the first preset format, generates journal file.Detection mark is used for The directory path information of destination folder is navigated to when being parsed to journal file and creates the process number institute of the file Row.Detection mark can be a fixed character or preset one section of sentence etc., this is not limited.This One preset format can be the form or other forms for being used to be spaced sentence for using punctuation mark as sentence interval, It is without limitation.
For example, the flow that application as shown in Figure 3 creaties directory, the flow specifically include:
Step S301 calls the mkdir interfaces of file classes.
The mkdir interfaces establishment file for calling File (file) common class using Amap is pressed from both sides, which is one A interface for establishing new file.It is most of complicated since File classes are a foundation class, and be the class that can be called frequently Operation is unsuitable for adding herein, such as database manipulation needs the method for context that can not use.Add in mkdir interfaces Add a log outputs.Since the running space of mkdir interfaces is still internal in application, that is, in Amap, so should Process where when log is exported is still application process, therefore:It is passed as detection and identified using fixed character.Such as:“twfx The app is Attempting to make a dir”。
Step S302 obtains No. pid and obtains file destination path.
The directory file path that will be created by the acquisition of mkdir interfaces.Such as "/storage/emulated/0/ autonavi”.The title autonavi of destination folder is further comprised in this full directory file path.Then it uses The pid of process where the current log of getpid interfaces acquisition, i.e. process number.Such as " 5968 ", it that is, creates when this document presss from both sides Process number is the file created by which application convenient for subsequent query.
Detection mark, path, pid are combined as character string, and export content using the character string as log by step S303.
Will detect mark, mkdir interfaces to be created catalogue fullpath, process number three parts content use ";" connection Get up, the content as log outputs.Finally the content of log outputs is:Detect mark+path+pid.Citing:twfx The app is Attempting to make a dir;/storage/emulated/0/iFlyIME;5968.
Step S304, creaties directory or file.
After log files are exported, Amap creaties directory or file, so as to which catalogue or document creation are completed.
It should be noted that institute of embodiment of the present invention illustrated example is only example effect, specifically application is not limited It makes, all applications in terminal device are suitable for the method that the embodiment of the present invention is provided.
Step S202 handles the row information where the detection mark of destination folder, obtains destination folder The process number of title and establishment file folder.
It is handled in the row information where the detection mark to destination folder, when being handled, is specifically as follows head First the row information where the detection mark of destination folder is decomposed according to default first form, obtains destination folder Directory path information and the process number for creating the file.Then according to the directory path information of destination folder, mesh is obtained Mark the title of file.
For example, by comprising detection mark row be stored as character string, into line character processing, first by the character string according to “;" be segmented, according to default first form, eventually it is divided into three sections.First segment is identified for detection, without being further processed. Second segment is the directory path information of destination folder, can obtain the fullpath of destination folder.Third section should to create The process number that file is.It can be obtained by the name of the destination folder according to the fullpath of the destination folder of second segment Claim.
Step S203 according to the process number for creating the file, determines the corresponding application packet title of process number.
, can be by the application belonging to pid query procedures after the process number for obtaining creating the file, and obtain and answer With packet name, it is hereby achieved that the corresponding application packet title of process number.
Step S204 establishes the title pass corresponding with the determining corresponding application packet title of process number of the file of establishment System.
After the title application packet title corresponding with determining process number of the file created, it is possible to establish The correspondence of the title of the file of establishment application packet title corresponding with determining process number, and the correspondence is carried out Storage, such as be stored in public database, it is inquired convenient for file manager.
For example, the title of the file of determining establishment as shown in Figure 4 application packet corresponding with determining process number The flow of the correspondence of title, the flow specifically include:
Step S401 starts detection service.
First, after system boot, start a service, illustrate entitled fileDetectService, and the effect of the service is Cycle performs and obtains newest log outputs.
Step S402 obtains log information.
For different size of log buffering areas, the log times length that can be stored is different, the buffering area for certain producer of illustrating The log of 10s can be preserved, in order to obtain all log, then the cycle period of fileDetectService can position 5s.
Step S403, parses log line by line.
Cycle every time, the log of nearest 10s first is obtained out by fileDetectService, and is parsed line by line.
Step S404 is judged with the presence or absence of detection mark in log, if so, S405 is entered step, if it is not, then entering step Rapid S404.
Detection mark (such as " twfx The app is Attempting to make are included when being resolved to certain a line content A dir ") when, this journey is individually stored and is further processed.It is third containing detection mark in following output log Row:
The first row:D twfx-block:startActivityLocked app:Com.hmct.vision userid= 0unlocked=false should_lock=false str=null
Second row:D twfx-block:IsFrontstack stack=Activity Stack { aea47bb Stacked=0,1tasks }
The third line:E system:twfx the app is Attempting to make a dir;/storage/ emulated/0/autonavi;5968
The third line statement namely detects the row information where mark.
Step S405 by label separating character string, gets pid and path.
Will comprising detection mark row be stored as character string, into line character processing, first by the character string according to ";" carry out Segmentation, according to our form, is eventually divided into three sections.First segment for void content with detection identify combination, this part without It need to be further processed.Second segment is the fullpath of establishment file, is denoted as path.The path is /storage/emulated/0/ autonavi.Third section is to create the process number of this document, is denoted as pid.The pid is 5968.
Step S406 obtains Path-sensitive address.
FileDetectService service acquisition Path-sensitives address can be that terminal device stores root herein:“/ storage/emulated/0”。
Step S407 judges whether include Path-sensitive in path, if so, step S408 is transferred to, if it is not, being then transferred to step Rapid S404.
Step S408 isolates the title of file from path.
Path is checked whether comprising Path-sensitive, if comprising, illustrate place that this document folder creates be we need into The position of row inquiry.Path-sensitive in path is removed, is exactly the relative directory and title of file.It is denoted as name.
Step S409 obtains the corresponding application packet names of pid or process name.
According to the application belonging to pid query procedures, and packet name is obtained, this two aspect of punishment:
First aspect:Using PackageManger application program management relevant interfaces, packet name is obtained.Such method can be with Obtain the packet name of application registered in android framework sides.
Second aspect:If first aspect can not get packet name, can by perform PS (Process Status, into Journey state) order, application process information is obtained, it is as follows:
u0_a111 5968 612 1197452 134924 sys_epoll_00f3ffc4c8 s com.autonavi.minimap。
Character string piecewise analytic can be carried out by space in PS information, final stage is exactly process name, if establish file Process be not a common application, can by process name but when a underlying services or executable file etc To know the title of the service.As can be known herein, entitled com.autonavi.minimap is wrapped in the application.
Step S410 is recorded as key-value pair in addressable tables of data using the title of file and using packet name.
It is recorded Bao Mingyu name as a matching list item in a region that can be inquired, in public database: Form is exemplified as:
Value (value):Com.autonavi.minimap, key (key):autonavi.The key and value is a key Value pair.
The storage mode of the tables of data is only a kind of example, without limitation, can also be other in practical application Storage mode come store above-mentioned folder name with application packet title correspondence.
Above-described embodiment shows the title by obtaining destination folder under root, according to the title of destination folder Folder name and the correspondence of application packet title are inquired, obtains and applies packet title corresponding to the title of destination folder, The title applied packet title, determine the application corresponding to destination folder according to corresponding to the title of destination folder.So as to Determining the destination folder is created by that application, inquires the source of this document, realizes the automatic knowledge of system application Do not go out true process or the application of establishment file.
